It's difficult to give a definitive answer here. It depends, of course, on each partner (individual trajectory, family and/or political culture...) and, I'd say even more, on each sexual encounter you have. What is tolerated, even appreciated, in a given situation (context, sexual games, excitement of the moment...), may be totally rejected at another time. It's important to remember that every sexual encounter we have is a unique alchemy with our partner, and, in human relations, that the same causes don't always produce the same effects.
Now, with practice, discussions before and/or after sex, reflexivity and careful attention to the weak signals emanating from our partner, we can "feel it" or not, during the sexual act, but there are still failures... Practice, practice, practice, that's the only way you'll become better.
